CARBURETER.

Original application filed December 16,

Specification of Letters Patent. Patented Apr. 18, 1916. 1912, Serial No. 736,996. Divided and this application filed June 18, 1913. Serial No. 773,412.

To all whom it may concern Be it known that We. WILLIAM SHAKE- SPEARE, Jr), and WILLIAM ScHM11),.citizens of the United States, residing at Kalamazoo, Michigan, have invented certain new and useful Improvements in Carburetors, of which the following is a specification.

This invention relates to improvements in carbureters.

Our improvements relate particularly to the carbureter shown in our ap lication for Letters Patent, Serial Number $36,996, filed December 16, 1912, the present application being a division of that application.

The main objects of this invention are: First, to provide in a carbureter, animproved means of supplying fuel for priming and starting the engine. Second, to provide an" improved carbureter which may be adjusted for different temperatures, so that the air supply is kept at approximately the temperature desired.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow. L

Ve accomplish the objects of our invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

Astructure which is a preferred embodiment of our invention is clearly illustrated in the accompanying drawing forming a part of this specification, iniwhich:

Figure I is a side elevation of our improved carbureter, the starting valve and air valve operating mechanism being shown in front elevation. Fig. II is a detail vertical section on a line corresponding to the broken line 22 of Fig. I, the various parts not especially related to the features of this application being omitted. Fig. III is a detail bottom view of the valve stem 3-1 and its actuating means. .Fig. IV is an end view of the air supply conduit and the inlet valve thereof. Fig. V is a vertical section through the air supply conduit of the carbureter and its valve, on a line corresponding to line 55 of Fig. I. Fig. VI is a front elevation of the primer and temperature control mechanism, with the index plate 22 removed. Fig. VII is a detail vertical section on a line corresponding to line 77 of Fig. I.

In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to-the drawing, the carbureter 4 body 1 is provided with an inlet passage or conduit 2 and a discharge passage 3 leading from the mixing chamber 4: above the valve seat. 5. I

The fuel nozzle and the air and fuel valves are not shown as they form no part of'this invention. The form preferred by us .is shown and described in detail in our application for Letters Patent above referred to.

To control the temperature of the air passing to the carbureter, the conduit 2 is provided with a cold air inlet 6 and a heated air inlet 7 adapted to be connected to a suitable source of supply, as a coil (not shown) heated by the exhaust. The

cold air inlet and the heated air inlet are both controlled by the cylindrical valve 8 .having a transverse port 9 of such length that the valve may be adjusted to admit both cold and heated air in varying proportions or to shut off the cold air or the heated air entirely and take only cold or heated air. hen the valve is adjusted so that the end 10 of its port strikes the stop 11, heated air only is admitted. Vhen it is adjusted so that the end 12 of its port strikes the stop 13, cold air only is admitted. See Fig. V.

The valve 8 is controlled by the lever 14 arranged in a convenient position, as upon the dash 15 of a motor car, when our improved carbureter is used on a motor car engine. The lever 11 is provided with a sleeve-like bearing member 16 arranged through the bearing 17 of the support 18 which is mounted on the front of the dash, the bearing 17 being arranged through the dash. On the rear ofthe lever bearing 16 is an arm 19 which is connected by the link 20 to the arm 21 on the valve 8. A dial plate 22, having suitable temperature indicia, as shown in Fig. I, is mounted on the support 18. .The edge of the dial is 14 is provided with spring pressed'pawl 24 adapted to engage the notches for retaining the lever in its adjusted positions. The lever finger piece 25 constitutes an index.

. The numerals of the index dial indicate the position the lever should be adjusted to for different atmospheric temperatures. For instance, the lever 14 is shown adjusted to 40 and the air inletvalve is opened to take heated and cold air, approximately half and half. In a temperature of 80, the lever would be adjusted to 80, at which point the heatedair inlet would be entirely closed At a temperature of zero, the greater portion of air taken Would be through the heated air port. At ten below zero, only heated air would be taken. This is found to'be a. very advantageous feature in the proper control and regulation of the carbureter.

The primer valve 26 is arranged in a valve chamber 27 provided therefor above the fuel reservoir 28. The chamber 27 is preferably formedin the Wall of the carbureter body, the valve seat 29 being formed in the wall of the body at the inner end of the chamber, as clearly shown in Fig. II. The valve chamber 27 is connected to the fuel reservoir 28 by the tube 30 dependinginto the reservoir. The valve 26 is held yield ingly in its seat by means of the coiled spring 31, one end of which bears against the c01 lar 32 on the valve stem, the other being seated in the closure 33 for the outer en of the chamber 27; The valve stem 34 roject's through this closure and is provided with a disk-like head 35 with which the eccentric pin 36 on the rotating valve actu: ating member 37 coacts. The valve actuating member 37. is supported 1n a bearing 38 carried by" the closure member- 33. The actuating member 37 is connected by the flexible shaft 39 to the. spindle 40 of the lever 41, the spindle 40 being journaled in the sleeve-like bearing 16 of the lever 14.

The lever 41 is provided with a lug 42 co acting with the lug 43 on the lever 14. These lugs engage when the levers are swung to certain positions. For instance, Whenthe primer control is adjusted to start the engine at 10 temperature, the alr control 1s shifted at the same time to the 10 position if it has notbeen'previously adjusted to such .position. The primer control le er may, however, be returned to its running posltion without moving the air control lever. When the lever 14 is swung against the boss-like stop 44, this also swings the lever 41 against the stop 45 or to its closed or runnmg position. By this arrangement a very effectlve priming is secured which greatly facilitates starting of the engine.

primer be opened during the last few strokes of the engine when stopping the same, the

or hot air or both simultaneously;

Further, if the fuel and connecting the primer valve thereto instead of the reservoir 28. As such an arrangement will be readily understood, we have not deemed it necessary to illustrate the same herein.

lVe have illustrated and described our improvements in detail in the highly satisfactory embodiment in which we have placed the same upon the market.

-lVhile we are aware that various modifications in structural details are'possible without departing from our invention, We believe that the disclosure made will enable those skilled in the art to which our invention relates to embody the same as conditions- .may require and have not, therefore, shown or described such modifications herein. We desire, however, to be understood as claiming our improvements specifically in the form illustrated as well as broadly Within the scope of the appended claims.
